(2y +1)(4y + 1) is the factored form
Step-by-step explanation:
the gradient of the line = 2 units/ 3 units = 2/3
i do believe the first one is D but im not sure about the 2nd <span />
Answer:
The answer is (-0.7, -9.4)
Step-by-step explanation:
1) Since we are using the substitution method, and we know that y = 2x-1, in the first equation, plug that into y. It should look like this:
4x-2(12x-1) = 14
4x -24x + 2 = 14
2) Combine like terms and continue to simplify until you get a direct answer for each variable.
-20x + 2 = 14.
-20x = 12.
x = -7/10 (or -0.7)
3) Now we know what x equals, so to find our y-coordinate, we will plug this into either equation.
y = 12(-7/10) -1
y= -84/10 -1
y= -9.4
4) Now that we have our x value and y value, we know our point. The solution is (-0.7, -9.4).
Answer:
148
Step-by-step explanation:
a straight line is always 180 degrees. therefore if you subtract 32 from 180 you are left with 148 degrees.
hope this helps
